摘要
太阳敏感器是卫星姿态控制系统中常用的一种光电敏感器。当卫星控制系统转入应急模式时,太阳敏感器的宽视场快速捕获太阳尤为重要。本文设计了一种梯形狭缝式太阳敏感器,该敏感器具有大的检测视场(157°)且可满足大太阳角(最大175°)下的应用,而采用梯形狭缝设计可大幅度减小太阳角大范围变化对太阳脉冲宽度的影响,从而便于后续处理电路的设计。实际的在轨飞行试验中验证了这种太阳敏感器的实用性。
Sun Sensor is a kind of popular photoelectric sensors in satellite attitude control system. It is very important to have a large field of view for the sun sensor during the course of the sun acquisition of the satellite working in the emergence mode. A ladder-shaped narrow slit sun sensor is presented, which has a very large field of view （157°） and is suitable for the application with the large attitude angle （≤175°）. The design of ladder-shaped narrow slit can decrease the sensor＇s output pulse widths which vary largely with the attitude angle, and be convenient for the correlative circuit design. The onboard experiment validates the practicability of the presented sun sensor.
